The world demand for energy is dramatically increasing. At the same time there is a growing need to protect our environment by increasing energy efficiency and developing “green” energy sources. Every year our resources of arable land, non-renewable energy, rainforest, and clean air and water, all significantly diminish. The conversion of light from the sun into electrical energy is playing a very important role in our current challenge for alternative energy technologies, to reduce our dependence on fossil fuels as well as reduce greenhouse gas emissions. Our research program opens new and exciting directions in the discovery of advanced materials and nanostructures to harvest energy. The strategy employed to make this outcome possible is through nanoscale and/or novel material synthesis, modeling, characterization, and fabrication of energy conversion devices.
My team’s expertise lies in vapor phase epitaxy (VPE) of III-V photovoltaic devices and nanostructures, novel photovoltaic structures such as the intermediate band solar cell, photovoltaic characterization as well as simulation and testing. Our work leverages student, faculty and industrial collaborators with a truly interdisciplinary nature spanning physics, engineering, materials science and chemistry. In addition, we have strived to use this research to further strengthen our student’s training as well as enhance RIT educational outreach and industrial collaboration. The results of our work are disseminated through both publication and collaboration with major photovoltaic and electronics manufacturers. The outcome of our work could advance the state-of-the-art in device efficiency and lower cost for the conversion of light to electrical energy.
The mission of our research group is to accelerate scientific breakthroughs in the discovery of nanoscale materials and structures that will advance the frontier of the conversion of light to electricity. Our focus is new materials synthesis, device modeling and simulation, solar cell device fabrication and demonstrating proof-of-principle of devices that will deliver a major boost to the world’s pursuit of innovative and transformative energy conversion products.
The vision of our lab is to elevate the vast, and essentially free, solar energy resource to a viable and sustainable alternative to fossil fuels. We will do this by developing new paradigms for photovoltaic conversion that enable use of highly efficient materials at low cost.
